Privacy
Policy

ZYKAY is committed to protecting your privacy. This policy explains how we collect, use, and protect information.

Collection and use

We only collect information required to operate the service, following a strict data minimization approach.

Zero PII storage

ZYKAY does not store personally identifiable information (PII). France Identité documents are processed ephemerally to generate cryptographic proofs.

Your personal data is never persistently stored on our servers. Only mathematical proof artifacts are retained.

Technical metadata

We retain only technical metadata needed to run the service:

  • Transaction timestamps
  • Blockchain addresses (Ethereum anchoring)
  • Temporary session identifiers
  • Cryptographic commitment hashes

Security and encryption

All communications use TLS 1.3. Sensitive identity payloads are encrypted with AES-256-GCM before network transit.
